Naya Rivera's upcoming memoir Sorry Not Sorry is spilling over with tea.

In her latest tease, the former Glee star dishes all about her ex-fiancé Big Sean, and how she caught him in a compromising position with a certain pint-sized pop star.
Apparently, the rapper's relationship with Ariana Grande started long before he and Naya broke things off.

"We'd been fighting for five straight days while he was traveling, and then on the one day that he was back in L.A., he said he didn't want to see me," she said, via Us Magazine. "Well, a*****e, I've got a key to your house."

After using her key, she wasn't too happy with what — or rather whom — she found chilling with her man.

"I walk in, go downstairs, and guess what little girl is sitting cross-legged on the couch listening to music? It rhymes with Smariana Schmande," she said.

The actress also revealed that she didn't even have a say in her split from Big Sean — that was all him.

"I learned that I was no longer getting married from the Internet, and at the same time as the rest of the world," she said in the book. "Not only were we no longer getting married, but apparently we weren't even together anymore."
